[nanomad]

https://github.com/nanomad/vue-cli-pwa-build-failure

Steps to reproduce

• Install latest vue cli 3.0.0-beta.
• Select the following features:
• PWA
• Use npm as package manager (but it happens with yarn as well)
• Use separated config files (just in case it matters)
• cd into folder
• run npm build

What is expected?

Build completes successfully

What is actually happening?

Build fails with the following error

> vue-cli-service build

Since it was working fine before, I suppose the PWA plugin is pulling in a transitive dependency that's not compatibile anymore...

[nanomad]

Found the issue:

• @vue/cli-plugin-pwa@3.0.0-beta.1 depends on:
  • workbox-webpack-plugin@3.0.0-beta.0 which depends on
  • workbox-*@^3.0.0-beta.0 which pulls in
  • workbox-*@3.0.0-beta.1 which is probably not compatible...

If I manually change the depenency to workbox-webpack-plugin@3.0.0-beta.1 then everything works. I suppose it's better if it was declared as ^3.0.0-beta.0
